If you already have a form and wanna post that to an update script, you could just add the student id as an hidden form element example:

Else if you want to redirect from another page to the update page, with a student id, the best way will probably be a $_GET variable. So the URL would look something like this: http://domain.com/update.php?student_id=1

And then your update.php will include a simple check like this.

if(!empty($_GET['student_id'])) {
    $student_id = $_GET['student_id'];
    // Ready to update
} else {
    // Throw 404 error, or redirect to an create page
}
